While most people tend to assume that movie-making is a fun business, with millions of dollars being handed out left and right and everyone having a great time, the reality of cinema can actually be very different.
Some films are real nightmares to make, with executive interference, moody actors, egotistical directors, and bad ideas souring the entire experience for pretty much everyone concerned. In fact, some of the most famous films ever made had some shocking behind-the-scenes stories, with many cast and crew members keen to finish filming and move on to something else as quickly as possible.
In some cases, directors or producers bite off more than they can chew. In others, their personalities clash with the cast and crew around them. Either way, the result is a highly difficult production process in which most people are pretty unhappy to head to work each day and eager to see filming finally come to an end.
Some of these movies turned out great when they hit the cinemas, while others were critical or commercial failures. In each case, however, they certainly weren't a lot of fun to make.
10. Jaws (1975)
It's the film that gave birth to countless lifelong fears of swimming in the sea, but by all accounts, Steven Spielberg's Jaws was an absolute nightmare to make. Technology and special effects in the 70s weren't what they are today, and the production was majorly troubled by the use of Bruce, which was the nickname given to the three mechanical sharks used throughout the film.
The trio of Bruces malfunctioned over and over again, and issues with these oversized props forced the film way over its budget. $4 million had been provided in funding, but $3 million was needed just to cover all the issues caused by the sharks.
Shooting a film at sea was also a highly ambitious undertaking and went pretty badly, with other vessels ruining shots, cameras getting drenched in water, and even one case when the boat used in the film started to sink. Photography was scheduled to last for 55 days but took nearly three times that amount, with lots of special equipment having to be designed and used to get all the underwater shots Spielberg wanted.
Crew members famously nicknamed the film "Flaws" as they suffered through one issue after another, and Spielberg admitted his inexperience and naivety played a part in the problematic production process.
